Diesel Vehicles
Due to new laws implemented by the U.S. Environmental Protection Agency, today's diesel vehicles are considered to be advanced fuel-efficient vehicles because they run on ultra-low sulfur diesel (ULSD), a clean burning fuel. Additionally, most diesel vehicles can run on biodiesel blends without engine modification.
